The Claim
Diet-induced thermogenesis is significantly higher for dietary protein than for carbohydrates and fats due to the higher energetic cost associated with the absorption, metabolism, and synthesis of amino acids from protein.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
The body uses more energy to process protein from food than it does to process carbohydrates or fats, resulting in greater heat production after eating protein.
See the scientific wording
Diet-induced thermogenesis is significantly higher for dietary protein compared to carbohydrates and fats due to the energetic cost of protein absorption, metabolism, and amino acid synthesis.
When you eat protein, your body breaks it down into amino acids, which must be processed by the liver. Excess amino acids are stripped of their nitrogen, creating ammonia, which is converted into urea using a lot of energy. This process, along with building new proteins from amino acids, generates heat as a byproduct, causing your body to burn more calories after eating protein than after eating carbs or fat.
What the research says
3 studiesThis study found that eating more protein makes your body burn more calories just to digest it, compared to eating the same amount of carbs or fat — which is exactly what the claim says.
Your body uses more energy to digest protein than carbs or fat — this study found that eating protein made people burn 6.44% of the meal’s calories just to process it, while carbs burned 3.5% and fat only 2.3%.
This study found that after eating a high-protein meal, the body burns twice as many calories digesting it compared to a high-carb meal, which means protein takes more energy to process.
